Purpose Our aim was to evaluate the clinical utility of b0EPI images obtained from diffusion sequence for the detection of the intracranial hemorrhagic lesions, especially acute
intracerebral bleeds thereby shorten the scan time particularly in the critical acute cases of stroke. Materials and methods Among all consecutive MR brain studies performed in our
department last year, we retrospectively selected those who followed the following criteria: (1) clinically suspected or radiographically confirmed acute infarction or hemorrhage. (2)
MRI imaging including DWI and T2∗ images. Sensitivity of hemorrhage detection, conspicuity of lesions, and diagnostic certainty were compared between the b0EPI and GRE sequences.
Results There were 77 hemorrhagic lesions with a variety of pathogeneses in various locations. 76/77 (98.7%) of these lesions were hemorrhagic (hypointense) on the GRE sequences,
whereas 61 (79.2%) were characterized as hemorrhagic on b0EPI images, and 16 (20.8%) were not detected. The overall difference in hemorrhage conspicuity/diagnostic certainty between
GRE and b0EPI sequences was statistically significant (P<.05). Conclusion b0EPI sequence, although shorter in acquisition time, was inferior to GRE imaging in the detection of acute and
chronic intracerebral hemorrhage. Keywords: Intracranial hemorrhage, Magnetic resonance, b0EPI, T2∗GRE

Learning objectives Magnetic Resonance angiography (MRA) is used in many institutions for initial evaluation of the cerebral circulation for patients with acute stroke.
Knowledge of the presence and clinical relevance of normal variants such as fenestrations, duplications, and persistent fetal arteries plays a crucial role in the diagnosis and
management of acute stroke and may aid in surgical planning. Our aims are :- - To review the spectrum of normal variant of the cerebral arteries at the MR Angiographic studies.
- To discuss the clinical implications of these variants. - To increase awareness and recognition of uncommon but normal vessels and their differential diagnosis
